Description

Thing networking body temperature subsides

Technical Field

The utility model relates to the field of medical equipment, in particular to thing networking body temperature subsides.

Background

The human body keeps normal body temperature, which is a necessary condition for ensuring normal metabolism and life activities. Therefore, the medical body temperature monitoring and analyzing instrument has certain medical significance for monitoring and analyzing body temperature and can be used for judging and positioning different physical sign states of human bodies. Body temperature is generally the temperature of the thoracic, abdominal and central nerves of the body, known as the core temperature, and is characterized by being relatively stable and higher than skin temperature. The tools and categories currently used for body temperature measurement can be divided into the following categories:

a mercury thermometer or a glass thermometer is made of glass and internally provided with a mercury column which increases with the temperature of a body. Mercury thermometers are widely used in the medical field and in ordinary households, and some pharmacies have available mercury thermometers. However, in view of the mercury hazard in mercury thermometers, banning measures have been taken in many countries, for example, as early as 1992, sweden banned the sale of all mercury-containing medical devices. The use of mercury thermometers is not forbidden in China, the mercury thermometers are widely used in the medical field and common families, and data from the institute of medical and instrument industries in China shows that 109.25 tons of mercury are consumed by producing the mercury thermometers nationwide in 2008, which is equivalent to the mercury consumption of 218.5 hundred million standard mercury-containing energy-saving lamps. About 1.2 million mercury-containing thermometers are produced in China every year, and more than 10 tons of mercury used as waste for treatment because of damage of the mercury thermometers in China every year.

The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button cell, an application specific integrated circuit and other electronic components. The electronic thermometer can quickly and accurately measure the body temperature, has the advantages of convenient reading, short measuring time, high measuring precision, memory and buzzing prompt compared with the traditional mercury glass thermometer, particularly does not contain mercury, is harmless to the human body and the surrounding environment, and is particularly suitable for being used in families, hospitals and other occasions.

Infrared thermometers are classified into contact infrared thermometers and non-contact infrared thermometers. The common contact type clinical thermometers include an ear thermometer and a forehead thermometer, and the accurate body temperature can be measured from the ear only by collecting time of one second. When in measurement, the temperature measuring head is inserted into the auditory canal, the temperature measurement of the upper end is pressed for one second, and the accurate body temperature of at least one bit after a plurality of points can be read from the liquid crystal screen. The most common non-contact infrared thermometer is a forehead thermometer which can remotely measure the temperature of a human body. The probe is only required to be aligned to the forehead, the measuring button is pressed down, and the measuring data can be obtained in only 2 to 3 seconds, so that the device is suitable for patients with acute and serious diseases, old people, infants and the like. However, at the beginning of use, the user may obtain several different measurement data because of the low familiarity with this operation, and generally the measured maximum value is the desired data.

The Bluetooth thermometer can realize real-time measurement of the body temperature of a human body, but the effective distance between the Bluetooth thermometer and a receiving terminal for transmitting data is generally 8-10 meters, and the transmission distance can be greatly shortened under the condition of a shelter.

In addition, the disposable thermometer and the temperature sensing film both utilize the temperature characteristics of the heat sensitive chemical material, and realize temperature measurement with different colors at different temperatures, but generally can only realize preliminary judgment on whether the body temperature is in a normal range, and cannot accurately measure the body temperature.

In summary, in the above measuring devices and methods, the conventional mercury thermometer and electronic thermometer are widely used in medical treatment and household, and have certain advantages mainly in terms of measuring accuracy and cost. However, these two measuring instruments cannot realize real-time measurement of body temperature (except for bluetooth thermometers), and in the medical industry, information is acquired mainly by means of on-site acquisition and manual entry by medical staff.

However, the effective distance for the bluetooth body temperature patch to transmit data is short, and in some application occasions, the position of the user is not constant, so that the corresponding whole set of equipment is required to be moved, which is very inconvenient, and if a patient needs to go to an operating room for operation or go to other departments for examination during hospitalization, the defect is very obvious at the moment.
